Book: Twenty Thousand Leagues Under the Sea

About two weeks ago i finished reading Twenty thousand leagues under the sea by Jules Verne. 

It's one of the classics on the science fiction genre, so there must be a lot of reviews and summarys of the book. One thing that i liked most is Verne's style, the mistery atmosphere that he puts around captain Nemo, and his ability to caught attention of the reader is an experience that i recommend you, reader.

The thing I want to bring about the Twenty thousand leagues under the sea and the journey aboard of the Nautilus, is the fact that Jules Verne was very precise about the scientifical data, he speaks about many existing animal species of the seas, also, he mentions natural phenomena as bioluminiscence, submarine volcaninc eruptions, oceanic streams (as that of Gulf), the iceberg phenomena and much more, simply outstanding. To express my point better, think of yourself today, you have internet wich means access to information, in addition put a very prolific scientific environtment(in comparison at least), with just few minutes in front of your laptop, you can get enough scientifical accurate information, so you can try to write some science fiction history. But now, think of yourself in the 1860 decade ('till 1870) and write that book.

It's worth to mention that the book has a lot of historical remarks wich reveals a writer with a huge literacy.

Interesting Phenomena
Maelstrom
Near the ending of the book, Verne mentions a phenomenon known as maelstrom (or maelström), a very strong whirlpool current near some Norwegian islands (near Lofoten island) is not considerated as a great harm for modern ships. See the video to get the idea

The phenomenom is caused by the encounter of currents flowing in opposite direction

Sargasso sea

Other interesting phenomena is the Sargasso Sea, a debris zone (my words) due to a circular loop of the Gulf Stream. A NOAA web page says 

The Sargasso Sea is a vast patch of ocean named for a genus of free-floating seaweed called Sargassum. While there are many different types of algae found floating in the ocean all around world, the Sargasso Sea is unique in that it harbors species of sargassum that are 'holopelagic' — this means that the algae not only freely floats around the ocean, but it reproduces vegetatively on the high seas. Other seaweeds reproduce and begin life on the floor of the ocean.
